A chilling prologue shows the lights going out globally as the GenSys-created simian flu decimates humanity. A decade later Caesar (Andy Serkis) is in command of the apes in the Bay Area forest, flanked by scarred warrior Koba (Toby Kebbel), wise orangutan Maurice (Karin Konoval), and loyal Rocket (Terry Notary). There is tension between Caesar and his petulant son Blue Eyes (Nick Thurston), and everything falls apart when Rocket’s son Ash (Doc Shaw) is shot by Carver (The Black Donnellys’ Kirk Acevedo). Carver is part of a team led by Malcolm (Jason Clarke), which includes Malcolm’s wife Ellie (Keri Russell) and son Alexander (Kodi Smith-McPhee). They are trying to restart a dam to provide power to San Francisco’s human colony led by Dreyfus (Gary Oldman). The dam is Caesar’s, and Dreyfus gives Malcolm three days to negotiate a peaceful solution…

Matt Reeves inserts some visual trademarks; a lengthy tracking shot in which chaos explodes into frame, a fixed-position sequence from a tank turret’s POV, and a nicely vertiginous use of the Golden Gate bridge; but whereas Let Me In’s slow-burning approach achieved agonising levels of suspense, this is just agonising – Reeves takes forever to unfurl a very simple and remarkably boring plot. Technically everything’s competent: Michael Giacchino’s music is effective if uncharacteristic (no sad tinkly piano!), and Michael Seresin’s cinematography approaches that of Ain’t Them Bodies Saints, and would be commendable if it likewise served a mood – but you can’t help feel it’s hiding creaking CGI. Ah, CGI… This is our defining modern paradox; an air of distancing unreality hangs over everything, but the great technology and preparation that created it is extolled as cutting-edge and therefore preferable to engaging verisimilitude achieved practically. The non-ending is as insulting as that of The Hobbit: The Desolation of Smaug, and a trend that needs to be denounced: it’s like ending The Two Towers halfway through the battle of Helm’s Deep.

Writing takes effort. 2011’s reboot had a shocking poverty of characterisation but was a roaring success. Writing becomes much easier for Jaffa, Silver, and Bomback if they know the audience doesn’t want characterisation… Blue Eyes is petulant. That’s his one note. Then later he’s cowardly. He’s easily duped, because… and sides with Koba, because… then finds his steel, because… the script said so. Koba recalls Firefly’s “Curse your sudden, but inevitable, betrayal!” He discovers Dreyfus’ preparation for war and returns to warn Caesar, but loses his rag because he sees Caesar helping humans; except Caesar’s not actually helping them when Koba arrives… But hey, in event of plot emergency break glass for jerk, right? Carver’s rejoinder to Ellie’s fact – “The virus was created by scientists I don’t think the apes they were testing it on had much say in it” “Don’t give me that hippie-dippy bullshit” – is comically awful, but it’s easier to have jerks spark plot points rather than have Dreyfus and Malcolm’s reasonable disagreement over how to achieve their aim be teased out; perhaps that’s why Oldman is barely in this movie. By the climactic “What are you doing?” “Saving the human race!” gambit we’ve reached a truly low point where self-sacrifice that doesn’t work (like Alona Tal in Supernatural) isn’t tragic, but a running gag from 21 Jump Street.

Dawn of the Planet of the Apes is so poor it makes you nostalgic for the awful Rise of the Planet of the Apes. Whither Rod Serling’s scripting intelligence?
